BACKGROUND Field

This application relates to passenger seats, and more particularly toheadrests of an improved type.

Background Technology

Passenger vehicles, such as aircraft, buses, trains, ships, andautomobiles, include passenger seats for passengers to sit in andutilize during travel. Passenger seats, such as passenger aircraftseats, are typically provided with a headrest that both provides apassenger with both protection by limiting rearward movement of thepassenger's head and comfort by providing a place for the passenger torest his or her head. However, common headrests insufficiently supportthe passenger's head, are not controllable by the passenger, and providelittle privacy for the passenger.

For example, some adjustable headrests have side wings that fold towardsthe head in the upright position. However, the side head supportcurrently offered in adjustable headrests does not suffice because theside wings are not dimensioned in such a way that it prevents the headfrom slipping away while leaning side ward, nor is the shape based onthe varying shapes and dimensions of the head. While other adjustableheadrests include one or two side wings of a bigger size to enableleaning, a passenger cannot choose to store away these side wings ifthey wish not to use them, for example if he or she wants to interactwith other passengers

As another example, previous attempts have been made to increase theperception of privacy, for example by providing a privacy screen betweenseats that passengers could let go up. Due to space limitations in theplane, however, these solutions are not widely implemented in economyclass cabins and moreover, the gesture of letting up a screen canfurther impede the yet delicate interaction between two passengers thatdo not know each other.

As a result, there is still a need for a headrest that caters to thesupport, privacy, and control aspects of passenger seats all at once.

DETAILED DESCRIPTION

The subject matter of embodiments of the present invention is describedhere with specificity to meet statutory requirements, but thisdescription is not necessarily intended to limit the scope of theclaims. The claimed subject matter may be embodied in other ways, mayinclude different elements or steps, and may be used in conjunction withother existing or future technologies. This description should not beinterpreted as implying any particular order or arrangement among orbetween various steps or elements except when the order of individualsteps or arrangement of elements is explicitly described.

The described embodiments of the invention provide seat assemblies traytable assemblies for use with passenger seats. While the adjustablesupport assemblies are discussed for use with aircraft seats, they areby no means so limited. Rather, embodiments of the adjustable supportassemblies may be used in passenger seats or other seats of any type orotherwise as desired. Directional references such as “forward,” “aft,”“up,” “down,” “top,” “left,” “right,” “front,” “back,” and “corners,”among others are intended to refer to the orientation as illustrated anddescribed in the figure (or figures) to which the components anddirections are referencing.

In one aspect, disclosed is a passenger seat headrest and associatedmethods, systems, devices, and various apparatus. The passenger seatheadrest can comprise an body and a side wing. The passenger seatheadrest can also comprise a dress cover. It would be understood by oneof skill in the art that the disclosed passenger seat headrest isdescribed in but a few exemplary aspects among many.

In one aspect, an adjustable headrest enabling sideward leaning andseclusion is disclosed. In one embodiment, the passenger seat headresthas side wings that pivot at the far ends of the seat, so as to enablesideward leaning without having to keep the head facing straightforward. In another embodiment, the passenger seat headrest relocatesthe pivoting points of the side wings to enable bigger side wings to bedeployed. The deployed side wings reveal a hammock construction which istensioned by deploying the side wing, as such creating a surface of thepassenger to rest his head, following the form of the head to a certainextent. The hammock construction is designed to cradle the side of thehead and cheek, as to prevent the head from slipping away while sleepingand reducing neck strain. In some embodiments, the passengers cancontrol the use of both or either one of the side wings. The side wingscan be stowed during takeoff and landing, which may not hamper cabincrew procedures according to some embodiments.

In various embodiments, the passenger seat head rest is adjustable. Insome embodiments, a designed consequence of deploying the side wings isthat visual shielding is provided at eye level of the passenger. Theside wings are shaped in such a way that a passenger is not completelyshut off from his neighbor, and can still see what is happening aroundhim at an up and downward angle. In some embodiments, the hammockconstruction is incorporated in the dress cover. In other embodiments,the hammock material may be designed to repel facial grease because itis configured to be more in contact with the face of the passengercompared to conventional dress covers.

In some embodiments, the headrest comprises a body with a side wing oneach side, pivoting at the ends of the body. The side wings can be adesigned to be either used in a stowed configuration (required duringtake-off and landing of the aircraft), where the side wings are foldedinwards and flat against the back structure of the seat, or in thedeployed position (for providing side support and privacy during theflight), in which case they are deployed to form side wings positionedperpendicular to the seat structure. These wings can be operatedmanually and each side can be deployed or stowed separately to theliking of the passenger.

In various embodiments, the body includes a back plate and each sidewing includes a side plate. In some embodiments, the plates are metal,although they need not be. The side plates can be connected by torquehinges to keep the side wings in the deployed or stowed configuration.The back plate can include holes for the attachment of a heightadjustment mechanism to be attached to a chair. Cushioning, such as foamcushioning, can be attached to the three plates and shaped in such a waythat a gradual transition between the portion supporting the back of thehead and the more protruding neck portion is provided in both stowed anddeployed configuration. A dress cover can cover the plates and foamcushioning and includes the hammock construction, which folds flat whenthe side wings are stowed.

The shape of the hammock construction and side wing can be designedbased on anthropometric dimensions of the passenger's head. It will beappreciated that the shape and design of the cushioning should not beconsidered limiting on the current disclosure. As one non-limitingexample, the cushioning may be designed to include a more gradualtransition between the side flaps and the back padding in the stowedposition, a more distinctly protruding neck bump along the entire widthof the headrest (including the side wings) and a different shape of theends of the side wings to provide more room and sturdiness for theattachment of the hammock construction.

It will further be appreciated that the material used to construct thedress cover should not be considered limiting on the current disclosure.As one non-limiting example, imitation leather may be used to constructthe dress cover. Other material may be utilized to construct the dresscover suitable for folding, operating conditions or load requirements ofthe headrest.

In some embodiments, the torque hinges may include a detent to limit themovement of the side wings to 90 degrees, such as to prevent excessiveforce on the hammock construction. The height adjustment mechanism,outer dimensions and shape of the headrest may be altered to suitdifferent seat models. The disclosed headrest provides head support andvisual privacy through the pivoting side wings revealing a hammockconstruction, thereby enabling sideward leaning and seclusion.
